Extended Bayesian network retrieval model based on synonyms
基于同义词扩展的贝叶斯网络检索模型

To capture relationships between terms by means of synonyms and introduce several modifications to the simple Bayesian network for information retrieval, an extended retrieval model that included direct relationships between terms was proposed. Experiment results show that good retrieval effectiveness can be achieved by adjusting the parameter of the Bayesian networks used in our model.
